Description

For the ValidateJSON processor, add support for flowfile attribute references that will allow for a JSON schema located in the Parameter Contexts, to be referenced dynamically based on a flowfile attribute. e.g. 

#{${schema.name}} 

 

The benefits of adding support for attribute references are significant.  Adding this capability will allow a single processor to be used for all JSON schema validation.  Unfortunately, the current version of this processor requires a dedicated processor for every schema, i.e. 12 schemas requires 12 ValidateJSON processors.  This is very laborious to construct and maintain, and resource expensive.
